DIY skateboard paint protectors

I have this idea of putting ducktape on places we're my skateboard get damaged the most such as the tail and nose. I'm thinking this will make it so I don't get any razor tail and could make my deck last longer (I have a landyaght cruiser and it getting some decent damage on the tail and a replacement deck cost 100 dollars so im just trying to save money) any thoughts on if this will work or not?
